. YARN-FEEDING DEVICE.

To all whom it may concern Be it known that I, GEORGE W. MoKnr' NEY, a citizen of the United States, residing 2 at Chester, in the-county of Delaware and State of Pennsylvania, have invented certam new and usefullmprovements 1n Yarn- Feeding Devices, of which the following is a other in order to attend tobrokenendslas they appear from time to time and, in view' of the factthat the attention of the opera-- tor is so widely diverted, it is impossible to quickly stop the machine or to move from one broken end to another. Thus great waste of yarn occurs andin addition to this the machines are often idle while entangled ends or other imperfections are remedied. V

In the above mentioned type of winding machines the ends of yarn have usually been fed thereto by first passing over a top rail or beam of the machine and then downwardly to the respective bobbins. Thisproduced a complete net work in front of the machine and as above-stated the wide space rendered it practically impossible-for an operator to quickly detect broken or defective ends of theyarn-while passing tov the bobbins.

One object of invention'isto provide improved means,for feeding yarn to winding machineawhich Twill be'so constructed and arranged that "it willreduce waste of yarn and timeand will also economize space.

Another object is to make my invention of a simple'and durable construction andso perfections in .the yarn and operation of the machine.

A still further objectisto so construct my quickly stop the invention that the ends of yarn will enter the winding machine-from one end thereof in the direction of the length of the machine and so that the ends of yarn. can be inspected Specification of Letters Patent.

'- while. occupying a comparatively narrow 1 space across which theoperator can easily reach for the purpose of removing any imperfections of yarn which'might occur as the latter passes to the Winding machine.

These objects, "and other advantageous ends which will be described hereinafter, I attain in the followingmanner, reference being had to the accompanying drawings in which- 7 Figure 1 is a front'elevation showing my improved yarnfeedingdevice in connection with a winding machine,

F igs. 2 and2 show a view of similar na' ture to Fig. 1 anddrawn on an enlarged scale illustrating the parts more in detail, Figs. 3 and 3 represent a top plan view of Figs. 2 and 2, i r Figi'is a transverse sectional elevation taken on theline' l-el of Fig. 2 and drawn on an enlarged scale, a I Fig. 5 1s a fragmentary top plan view of Fig.4, p 1

*ig: 6. is a fragmentary perspective view of certain of the parts of my invention, and

Fig. 7 is an elevation of a dividing or combing-reed which I preferably employ.

Referring to the drawings, 8 represents a winding machine having a plurality of tiers 9, 10 and 11,each ofthe tiers having two rows '12 and 13 of spindles upon which bobbins'rl aremount'ed. Theseflspindles are rotated by means of belts 15 which pass over drums 16 arranged atdifferent elevations, as clearlyshown in Fig. 4. A motor 17 is illustrated as operatively'connecting- 'thedrums 16 for the "purpose of rotating the drums. A number of lifter rods 18 are adapted to be raised" and lowered; bymechple the'lifter-rods 18 can be, guided and operated by'any-well' known means'such for example as the guiding and operating de vices disclosed in United States Patent, No. ..1,137,514. that the operator can easily detect anyimqtween the rows'12 and 13 of spindles ofeach anism not illustrated and said mechanism 7 can "be of the type usually employed in winding machines for raising and lowering thelifter rails and yarn guides. For examof the tiers 9, l0, and 11; and "these channels sides as clearly'shown in Fig. 6.

A stand 522 is preferably made of frame work and includes a standard 23 which has have yarn guides20 and 21 securedto their a large eyelet or guide Mat-its top; A hum l ber of pins extendoutwardly from. the

standard 23 below the guide 24 and provide verse rungs 28 spaced apart and located atv one side of the pivot 27. The rails 29 of the stand 22 has bars or rungs 30 extending therebetween and below the rungs 28 of the beam 26, as clearly shown in Fig. 2. The ends 31 of the yarn are grouped and pass through the guide 24 and thenin a zig-zag manner alternately between the pins 25 of the rack 25*. After leaving the rack 25 the group of ends pass downwardly under one of the rungs 30 and then upwardly over one of the rungs 28 of the beam 26, then down wardly under another one-of the rungs 30 and again upwardly over the other rung 28 of the beam 26. Erom the latter mentioned rung 28 the ends pass downwardly to the other of the rungs 30 and then upwardly over a roller 32. The beam 26 at the opposite side of the pivot 27 is preferably notched as shown at 33 and a suspended weight 34 is adapted to engage any of the notches 33 at various distances from the pivot 27; said weight serving to move the and 37 journaled in its top, and a bracket 38 projects from the stand35 toward the stand 22. The bracket 38 includes a substantially horizontal arm 39 which is V- shape in top plan view as shown in Figs. 3

and 3. The arm 39 forms a support for a dividing or combing reed 40, said reed having splits4l between which the ends of yarn 31 respectively pass. The reed 40, as illustrated, is in a position below a plane includ ing the axes of the rollers 32 and 36 so thatthe ends of. yarn in passing fromthe roller 32 are compelled to extend downwardly through thereed andthen upwardly over the roller 36, as clearly shown in Fig. 1.

' Thewinding machine 8 has a plurality'ofrails 42 projecting therefrom towardthe stand 35 and said rails at their outer ends have collective guides or eyelets 43; said guides or eyelets 43 being insubstantial alinement with the respective channels19.

The ends of yarn are divided into smaller "groups 44 due to'the fact that a number of the ends pass through each of the guides or, ,j eyelets 43; After passing overthe roller 36,

certain of the smaller groups 44 pass under roller 37 while others pass over said roller 37 according to the height of the guides 43 through which they must pass. Each of the channelsi19 has a main eyelet 45 positioned at its end nearest-the stand 35 and through these eyelets 45 the respective groups 44 of yarn ends. pass into the channels 19. After passing through the main eyelets 45 the ends of yarn pass through the yarn guides 20 and 21 on opposite sidesof the channel and from thence to the bobbins of the rows 12' and 13. Theyarn guides 20 and 21 are not directly opposite each other as clearly showninFig. 5. On the contrary, the yarn guides 20 occupy a slightly advanced position so that during the wmdmg of the respective bobbins the direction or angle of the yarn in extending from the yarn guides to the bobbins will be substantially the same at different times during the building of the tapered shape of the bobbins as illustrated in Fig. 4.

A foot rail 46 is'mounted on antifriction rollers 47 directly in front of the arm 39, and an operator standing at the side of the arm 39 can easily move the foot rail 4-6 lengthwise. The foot rail 46 is connected by an arm 48. to a switch 49 which controls the operation of the motor-17. Thus an operator in watching the yarn as it passes through the splits of the reed 40 can quickly stop the machine 8 by a movement of the foot'on the rail 46 if'any imperfection of the yarn is noticed as it passes through the straight reed 40. It will be noted that the reed 40 is free to be moved lengthwise along the arm 39 for the purpose of combing or separating any ends of yarn if they should happen to become entangled and if neces sary the reed 40 eanbe bod1ly lifted from the arm 39 to facilitate the combing action.

During the feeding of the yarn the channels 19 with the yarn guides 20 and 21 thereon receive an upward and downward movement due to the action'of the lifter rods 18 to cause the yarn to be fed to the bobbins throughout their height; Furthermore by arranging two rows of bobbins in each tier and providing asingle channel 19 therebe- -tween a great numberof bobbins canbe operated in a comparatively small space and with comparatively few operating parts since the limiting rods of each tier cause the feeding of the yarn to two-rows of bobbins. In addition to this, the inclusion of the channels provides a housing for the ends of yarn and eonfines smaller groups 44 within limited space free of any projections and so as to provide asmoothsurface with which the endsoffyarn can. contact without injury thereto.

While I have describedmy invention as taking a particular form, it will be understood that the various parts of my inventionmay be'changed without departing from the spirit thereof, and hence Ldo not limit myself to the precise constructionset forth, but consider that I am at liberty to make such changes and alterations as fairly come within-the scope of the appended claims.

Having thus descrlbed my invention, What I claim as new and desire to secure by Letters Patent is 1. A winding machine including a row of winding elements; a collective guide arranged adjacent the end of said row; means located adjacent the end of the machine for delivering yarn in the direction of the length of said row through said collective guide whereby a group of ends passes substantially parallel to said row; and other guides spaced apart for directing the ends from said group to the respective winding elements; substantially as described.

2. The combination with a winding machine including rows of winding elements arranged in tiers; collective guides adjacent the ends of each tier; means for separating the ends of yarn, said ends after being separated passing in groups through said guides and other guides spaced apart within the length of the tiers for guiding the ends "from said groups to the respective winding elements of each tier; substantially as described. v 1
